I was a Senior Lecturer (now retired) in the School of Computer Science and Electronic Engineering, University of Essex, UK. I'm interested in railways and transport, electronics and computers, programming, digital signal processing, some mathematics. For more details see my personal web page. I don't have a lot of time to edit Wikipedia pages, but if I spot something while I'm reading stuff, I'll usually fix it.
